This term we will be looking at the violent side of Planet Earth. We will take a journey to the centre of the Earth. We will marvel at volcanoes and try to outwit earthquakes. Violent Earth N To describe the structure of the Earth To explain how and why plates move To discover the supercontinent of Pangea What’s at the centre of our Earth? Key terms: Crust, mantle, inner core, outer core, plates. TASK Complete the mindmap below with a partner Nuclear war World wars Global warming Tsunamis Earthquakes Volcanoes What is the greatest threat to life on Earth? Tornadoes Pandemics Floods Hurricanes Zombies? Is our Earth itself the greatest threat to life? These are all images of tectonic hazards. Tectonic hazards are created when the surface of Earth breaks open or moves! To find out why the Earth moves we need to look at its structure. The Structure of Earth TASK Fill in your structure of the Earth sheets The Layers of the Earth Rap Throw your hands up for the layers of the Earth! Throw your hands up for what’s below the surface! Throw your hands up and let’s discuss… The inner core, outer core, mantle and crust! As you listen to the rap, write down five NIFs (new interesting facts) about the layers of the Earth. The Shattered Crust The crust is made of rock. But it is not a smooth, unbroken surface. The crust a cracked, broken surface like a jigsaw. Each broken piece of the crust is called a plate. The Plates Eurasian North American Pacific South American African Plate Nazca Indo Australian Plate Antarctic TASK QUESTION Label your What plates do these map. arrows What show? are the plates named after? An Earth on the Move NEWSFLASH The surface of the Earth moves! At the rate your finger nails grow. HOW DO WE KNOW THIS? Because the continents used to WHY DOES THE SURFACE MOVE? be joined Because the crust is broken together! Look at South America and into plates and… Africa. They fit The plates sit on top of together! The the mantle. This is a world used to look molten layer that moves! very different. Watch the PANGEA CLIP. Recap Questions 1. Can you name the layers of the Earth? 2. What is the crust broken up into? 3. How many plates can you name? 4. What evidence is there to tell us that the continents once joined together? 5. Why do the plates move? 6. How quickly do the plates move?
